Abstract

A revision of taxonomic structure of Phrynocephalus arabicus Anderson, 1894 complex was presented in our previous paper. However further investigations showed that specimens from southern Arabia do not refer to one species. A new species from Al Sharqiyah Sands, northeastern Oman is described. It differs morphologically from all other representatives of Ph. arabicus complex by body and tail proportions, dorsal coloration, undertail coloration and genetic characters. Phrynocephalus arabicus sensu stricto is distributed in Yemen, southwestern Oman, UAE, and southern Saudi Arabia. Phrynocephalus nejdensis Haas, 1957 is valid species, based on the morphological and genetic difference. Taxonomic status of Phrynocephalus macropeltis Haas, 1957 needs further confirmation with material from the type locality.

Keywords: Squamata; Acrodonta; Agamidae; Phrynocephalus sp. nov.; Al Sharqiyah Sands, northeastern Oman


Phrynocephalus sakoi sp. nov. 

Holotype: ZISP 28705, adult male (Fig. 4).
Paratypes: ZISP 28706 – 28710, ZISP 27089, CAS251008, 251022, 251023 (Fig. 5, Table 3).

Type locality. Al Sharqiyah Sands, Filim vicinity, northeastern Oman.

Diagnosis. A large and “heavy” Phrynocephalus species  with  tail  longer  than  body  in  both  sexes;  five-star shape bright orange pattern on head in females and black in males, two bright orange stripes on the neck in female sand black in males, two longitudinal rows of six bright orange (salmon) patches on the dorsum in females and black in males; with white under tail coloration without bands in both sexes with black distal third in males and black quarter in females  (two  bands)  and  no  bands  in white proximal part.

Etymology. Species dedicated to the memory of our close friend and colleague Sako Tuniyev, who tragically passed away on January 5, 2015. His death was shockand big tragedy for all who know him. The new species dedicated to the memory of young zoologist in the beginning of his carrier, with many fresh ideas and new collaborative projects, to a good son of distinguished father, to a father of two kids and a good husband, to our brother and colleague. We will always keep him in our hearts

Distribution. Species expected to be isolated in Al Sharqiyah Sands, northeastern Oman.

DISCUSSION: Additional studies of Ph. arabicus sensu lato from southern Arabia showed that it is polytypical complex. Ph. sakoi sp. nov. from Al Sharqiyah Sands is characterized by morphological and genetic differences. This isolated desert consists of many large North-South linear dunes that are separated from each other by 2–3 km intervals (Radies et al., 2004; Edgell, 2006). A new species of endemic gecko Stenodactylus sharqiyahensis was also described from the Al Sharqiyah Sands (Metallinou and Carranza, 2013). Arabia is characterized by high speciesdiversity of lizards, as indicated by descriptions of manynew species in the last years (Carranza and Arnold, 2012; Melnikov and Pierson 2012; Melnikov et al., 2012a,2013a, 2013b, 2014; Nazarov et al., 2013). Some areas like Al Sharqiyah Sands are characterized by high level of endemism and needs special study. 

According to the molecular phylogenetic analyses and morphological results Ph. arabicus complex represent at least four well distinguished taxa. They are: Ph. arabicus sensu stricto from the southern Arabia (Yemen, southwestern Oman, southern Saudi Arabia, UAE), Ph. nejdensis from the northwestern Arabia (southern Jordan, northern and central Saudi Arabia), Ph. ahvazicus from the northwestern Iran, and Ph. sakoi sp. nov. represented by an isolated population in the Al Sharqiyah Sands, northeastern Oman. This four species are divided into two groups: southwestern Arabian Ph. arabicus + northeastern Arabian Ph. ahvazicus and northwestern Arabian Ph. nejdensis + southeastern Ph. sakoi sp. nov. Taxonomic status of Ph. macropeltis from the eastern coastal Arabia (eastern Saudi Arabia) needs further confirmation with material from the type locality (work in progress).

[Herpetology • 2015] Pseudotrapelus chlodnickii • Red'n'blues: A New Species of Pseudotrapelus (Agamidae, Sauria) from Sudan, Africa


Pseudotrapelus chlodnickii
Melnikov, Smielowski, Melnikova, Nazarov & Ananjeva, 2015

ABSTRACT 
A new species of Pseudotrapelus from Sudan, Africa is described. It differs morphologically from all other Pseudotrapelus species in its unique coloration — chocolate-red with white ocelli, also in its 3rd toe being longer than the 4th (but 16 lamellae under the 4th toe), and in one row of 6 unseparated precloacal pores in males. This new species also has 14.3% genetic divergence from P. sinaitus, and 14.7% from P. aqabensis, P. dhofarensis, and P. jensvindumi (by mtDNA COI gene). Taxonomic relationships of African Pseudotrapelus need further investigations.

Keywords: Squamata; Acrodonta; Agamidae; Pseudotrapelus sp. nov.; Africa; Sudan.

[Herpetology • 2008] Species of Acanthosaura Gray, 1831 (Agamidae: Sauria, Reptilia) of Vietnam: Results of molecular and morphological study


Abstract
On the basis of morphological and molecular data, taxonomic diversity of the agamid genus Acanthosaura in Vietnam is discussed. This genus is represented in Vietnam by four species of two complexes, A. capra and A. lepidogaster. DNA analysis and the absence of reliable finds suggest to exclude A. crucigera and A. armata from the faunal list of Vietnam. The recently described species A. nataliae Orlov, Nguyen and Nguyen, 2006 of the A. capra complex is considered. Two species are recognized in the A. lepidogaster complex, one of which, A. coronata Günther, 1861, Smith (1935) regarded as a synonym of A. lepidogaster (Cuvier, 1829).

[Herpetology • 2006] Acanthosaura nataliae • A new Acanthosaura allied to A. capra Günther, 1861 (Agamidae, Sauria) from central Vietnam and southern Laos


Acanthosaura nataliae Orlov, Truong & Sang, 2006

A new agamid species from central Vietnam and Southern Laos is described. It is distinguished from A. armata, A. coronata, A. crucigera, and A. lepidogaster by lacking a spine on the occiput between the tympanum and nuchal crest. The new species differs from coronata and lepidogaster by having a large crest and from armata, crucigera, and lepidogaster by lacking a dark marking on the nape. It most closely resembles A. capra, but differs from it by having large keeled scales intermixed with small scales on the lateral and dorsal surface of body (scales relatively uniform in capra). Strong difference in coloration in live of adult males and females of compared species of genus Acanthosaura are described.

Etymology. The specific epithet is a matronym for Natalia Ananjeva (Zoological Institute, Russian Academy of Sciences, St. Petersburg, Russia) in recognition of her many contributions to the study of agamid lizards.

[Herpetology • 2005] Bungarus slowinskii | Red River krait • A new species of krait (Squamata: Elapidae) from the Red River System of Nothern Vietnam



Red River krait | Bungarus slowinskii 
Kuch, Kizirian, Nguyen, Lawson, Donnelly & Mebs 2005

We describe a new species of krait (Elapidae: Bungarus) from the Red River drainage in northern Vietnam. The new species differs from all congeners except its sister species Bungarus bungaroides by the combination of divided subcaudals, dorsal scales arranged in 15 rows, black and white rings on body and tail, and in color pattern of the head as well as hemipenis morphology. The new species differs from B. bungaroides, a distantly allopatric species ranging from eastern Nepal to northern Myanmar, in molecular characters and color pattern. We propose a vicariance hypothesis in which speciation coincided with the uplift of intervening mountain ranges in southwestern Yunnan (China) and/or Late Tertiary glaciations.



Etymology: Named after Joseph Bruno Slowinski (1963-2001), American herpetologist, who died from snakebite at age 38. For an obituary see Donnelly & Crother 2003. For more biographical details see James (2008).
